The term "Kabbalah" was originally used in Talmudic texts, among the Geonim, and by early Rishonim as a reference to the full body of publicly available Jewish teaching. In this sense Kabbalah was used in referring to all of known Oral Law. Over time it became a reference to doctrines of esoteric knowledge concerning God, God's creation of the universe and the laws of nature, and the path by which adult religious Jews can learn these secrets.
